BUILDER-MOTION.

Specification of Letters Patent.

Application filed Hay 5, 1914. Serial N 0. 836,391.

To all whom it may concern:

Be it known that I, GEORGE S. HARRIS, a citizen of the United States, residing at West Point, in the county of Troup and State of Georgia,have invented certain new and useful Improvements in Builder-Motions; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others, skilled in the art to which it appertains, to make and use the same.

The invention to be hereinafter described relates to spinning or winding machines, and more particularly to the builder motions employed in such machines for giving to the yarn a distinctive traverse during certain preliminary windings to form a bunch and upon the substantial completion thereof to automatically resumeV the regular traverse to complete the load upon the bobbin.

Various forms of mechanism have heretofore been devised to provide a bunch upon the bobbin near the base portion thereof and then to build up the bobbin with a regular traverse, and an example of such mechanism is found in the prior patent to George S. Harris,No. 1,167,168, dated January 4, 1916, to which reference may be had. It is desirable in some kinds of wound bobbins, that the bunch be formed by relatively short traverses of the yarn until the bunch has assumed the desired size, and that then the yarn traverse be modified so as to merge into the service wind which is finally attained and continued until the bobbin is fully wound. Y

An important feature of the present invention, therefore, consists in efficiently controlling the traverse of the ring-rail or yarn guide, for producing a feeler bunch at or near the base of the bobbin and then building up the bobbin in the regular manner.

Another important feature of the invention consists in imparting the bunch buildermovements to the ring-rail or yarn guide by a rigid member interposed between the builder motion devices and ring-rail traversing devices, and automatically rendering said rigid member inoperative', when the bunch is completed.

Other features of the invention in addition to the above will be hereinafter described in connection with the accompanying drawings which illustrate one good practical form of the invention, it being understood that changes in the means shown may be made within the true scope of the invention as defined by the claims.

Referring to the drawing by numerals, 1 l

indicates the frame of the .machine to which is fixed a bracket 2,- in which is journaled a pulley or drum 3. A buildermotion letoif mechanism, not illustrated, but of any ordinary type, sucha as that shown in the patent hereinbefore mentioned, has its chain cable 6 extending and fixed to the pulley or drum 3, and a builder chain cable 7 laps that portion of cable 6 wrapped about pulley or chain 3, and the cable 7 is also fixed to the pulley 0r drum so that the longitudinal reciprocating movement of the cable 6 as determined by the builderI motion devices is imparted as an oscillatory movement to the pulley or drum and therefrom to the cable 7 as a reciprocating movement. Cable 7 engages the usual quadrant 8 carried by the arm 9 which is fixed to the shaft 10. The shaft l0 is engaged by an arm 11 provided with a counter-balance weight 12, and the shaft also carries a pusher rod lever 13 engaging the pusher rod 14, which in turn, engages the yarn guide or ring rail 15. The structure thus far described is of ordinary form and the operation is well known, consisting in the swinging of the quadrant 8 by the cable 7, the weight 12 causing an oscillation of the shaft 10 when permitted by the movement of the cable 7, and the cable itself imparting the return oscillation to the shaft 10, so that the ring-rail 15 is lifted by the action of the weight 12 and is lowered by gravity through lack of support by the rod 14 when the weight 12 is being lifted by the action of the cable 7. "The cmmon practice of effecting a uniform reciprocation of the cable 7 so that the distance traveled by the ring-rail at any one time is the same as with each stroke than with the preceding stroke, and esc-ends a proportionately less distance so that the ring-rail 15 makes a gain at eachstroke, as well understood.

A bracket 'or arm 16 is lixed to the arm 9 and is provided at its upper portion with a longitudinal slot 17 through which extends the bolt 17 which bolt also extends through a slot 18 in a link or rigid member 19. The bolt 17 is engaged by a nut at its outer end and at its inner portion is formed with an integral or fixed flange 17a engaging the bracket or arm 16 for enabling the nut -to clamp the bolt at any point of adjustment along the slot 17 A stud or portion 17 b extends inwardly from the inner face of the flange 17EL through the slot 18 of a link 19, and a washer 17? engages the inner face of the link or rigid member 19 for preventing the link from becoming displaced., a set screw 17 d engaging and retaining the washer in position. The link 19 is a rigid rod or bar and extends from the pin 17 past the pulley or drum. Preferably, the link 19 is formed of two lapping sections, one having slots 19 and the other carrying bolts 19 which extend through the slots for rigidly clamping the two sections together at any desired point of adjustment. This adjustment enables variations in the length of the link 19 corresponding with variations in the length of the chain 7, due to adjustments or wear thereof, and the in-and-slot connection of the parts of the link 19 also facilitate accurate adjustment of a new link to an old machine. The free end portion of the link or rigid member 19 is supported by the pin 20 extending laterally from the face of the pulley or drum 3. A notch 21 is formed in the lower edge of the link or rigid member 19 in position for at times receiving the pin 20. A spring 22 is fixed to the bracket 16 and engages the link 19 and is tensioned toV exert pressure longitudinally of the link toward the bolt 17. The weight 12 is proportioned to exert force sufliciently exceeding the force of the spring 22 to insure retention of the bolt 17 at the right hand end of the slot 18 so lon as the pin 20 is engaged in the notch 21. T e pin 20 and notch 21 may be formed as desired, but a particularly eicient. construction of these parts is the provision of a box sleeve 20 for the pin 20, (seen in Fig. 3) and a squared shape for the notch 21 corresponding to the angular formation of readers the exterior of Athe sleeve 20 so that whenever the lower edge of the link 19 passes the plane of the axis 'of the pin 20, the sleeve 20will revolve as the link 19 is drawn longitudinally by the springs 22. This occurs only after the completion of the bunch The pulley or drum 3 carries a release memberV consisting of a plate 23 having a longitudinal slot 2t through which extends retaining bolts 25 adapted to clamp the plate against the face of the pulley ordrum 3 at any desired point of adjustment. @ne end of the plate 23 is beveled to form an inclined surface 27 adapted to engage the overhanging portion of the link 19' after the pulley or drum 3 has acquired a given amount of gain (when the bunch is completed) and to thereupon lift the free end of the link 19 for disengaging the notch 21 from the pin 20. The link, being thus left free, will be pulled longitudinally back by the spring 22 a distance sufficient for carrying the notch 21 back away from the pin 20, so as to prevent the notch 21 from again engaging the pin 20 on the returning movement thereof. The link is of sufficient length beyond the notch 21 to slide on the sleeve 20 of the pin 20 after the notch 21 has been pulled back out of the path of the pin 20 by the spring 22. This movement ofthe link 19 is accommodated by the slot 18.

Thus in operation, in winding a traverse 4down for dofing the fullbobbins, the

rail 15 is depressed below the starting point by manually depressing the lever 13 and the lifting rod 14, which produces a longitudinal thrust of the link 19 in a direction to the left, Fig. 1, for moving the notch 21 into engagement with the pin 20. When the notch 21 yhas engaged the pin 20, and thevwound bobbins have been dotted, the lever 13 is released, and the weight 12 thereupon drops, thereby elevatingy the guide or` ring-rail 15 to the starting point, and placing the spring 22 under tension by moving the pin 17 to the rear end of the slot 18. At the beginning of the next spinning operation, the link or rigid member 19 will control the traverse of the ring-rail 415 with each stroke of the builder mechanism letod', thereby/'allowing the cable 7 to remain slack and sag, until the part 27 of the plate 23 strikes the link and releases theengagement of the notch 21 with the pin 20. During the restricted movement, the short traverse necessary for building the` bunch is had and this restriction in the traverse of the ring-rail is due to the fact that the transmission of motion is through a shorter radius on the pulley or drum 3 and a longer radius on the quadrant 8. The length of the traverse, therefore, can be varied by adjustment of the bolt 17 along the slot 17. As soon as the link 19 is lifted by the plate 23 so that the notch 21 is freed from the pin 20,

the control of the quadrant is restored to the flexible connection or cable 7 and its connected ulley or drum 3 and winding continues undbr such control until the bobbins are completely wound. The notch 21 will not again engage the pin until the link 1Q 1s manually thrust forward by the depressing lever 13 as above explained.

When it is desired to vary the length of traverse during the bunch-building period, it is necessary only to adjust the bolt 17 along the slot 17', movement of the bolt upwardly in the slot decreasing the length of traverse, and adjustment of the boltdown the slot increasing the length of traverse.

A bracket 26 is provided and formed with a slot 26 through which the link 19 extends, so as to serve as a guide for the link. The bracket 26 is adjustably fixed in place by a retaining bolt 2 extending through the slot 2 in the bracket 26 and engaging bracket 2.
